1.In which of the following reactions can equilibrium not be established?a.NaCl+AgNO3→AgCl+NaNO3\mathrm{NaCl} + \mathrm{AgNO_3} \rightarrow \mathrm{AgCl} + \mathrm{NaNO_3}NaCl+AgNO3→AgCl+NaNO3b.HCl+NaOH→NaCl+H2O\mathrm{HCl} + \mathrm{NaOH} \rightarrow \mathrm{NaCl} + \mathrm{H_2O}HCl+NaOH→NaCl+H2Oc.H2SO4→2H++SO42−\mathrm{H_2SO_4} \rightarrow 2\mathrm{H^+} + \mathrm{SO_4^{2-}}H2SO4→2H++SO42−d.All of theseLogin to continueOnly logged in users canattempt or see the solution.
